Title: Mikronik Infinitiv 1200 tower and A4000 keyboard
Post by: starf81 on June 19, 2005, 01:47:16 PM

Is it possible?

During this week I'll receive one of this tower for my A1200 and I'd like to use an original Amiga keyobard.

Since I already own an A4000 keyboard, can I use it?

Thanks!
Alex

Don´t know for sure, depends on the keyboard controller. But you can use any other pc keyboard and certainly the old ones with Din plug  :lol:

Yes, that's sure... but a PC keyboard is not good on Amiga  :-D

Otherwise, excluding the Micronik controller, is it possible to put a PS/2 connector on 1200's motherboard to connect directly the 4000's keyboard?

I have a Micronik A1200 with Z2 busboard and the keyboard input thingy on that only accepts PC keyboards. And it doesn't even support multiple keypresses :\. I also have a kit for making the A1200 KB into a standalone PC keyboard, it has a PIC microcontroller onboard.

i had one of those. (Micronik kit that took the A1200 keyboard into a separate case)
it (the controller board) fried very quickly..

i got some other device that sat on top of the chip on the motherboard and use an old AT keyboard..

i have an A2000 keyboard here that i'd be happier using though..

Yes... but is it possibile to add a simple PS/2 connector to the 1200's mobo to link directly a standard external Amiga keyboard like the A4000's one?

The A4000's keyboard has its internal chip to control keys activities while the 1200 has it directly on the motherboard, so I don't know if it can create a conflict between them. But I'm pretty sure that we can find a way to solve this little issue!  :-D

I want try to explain me better: my idea is to exclude the Micronik keyboard controller and add a new one. And, I think, since I should use an original Amiga's keyboard, it'll not require a controller but a simple connector.
Now, the problem is: where do I have to solder the wires of PS/2 female plug?  :-D

I don't know if your idea would work, but I do know that I have a keyboard adaptor sitting here, aimed at A1200 computers for usage with an external keyboard (A2/3/4000 keyboards) and it has it's own controller chip on the board.

The board has a ribbon like the one going from the A1200 desktop keyboard and into the white socket. And it has connectors for LEDs aswell, so any tower LED would work with it :-)
